STAND FOR TESTING AC AND DC MOTORS Russian patent published in 2018 - IPC G01R31/34 

FIELD: testing equipment.

SUBSTANCE: invention relates to a testing technique and is intended primarily for testing switch motor. Essence: the stand contains control and display panel (5) connected to controller (9), personal computer (3), voltage regulator (14), generator (7) and tachometer (8). Controller (9) is connected to personal computer (3), first and second switches (10, 11), and inverter (12). With the output of voltage regulator (14), the inputs of first and second autotransformers (15, 16) are connected. With the output of first autotransformer (15), first ammeter (18) connected to first switch (10) and voltmeter (19) are connected through first rectifier (17). Second autotransformer (16) is connected via second rectifier (20) to second ammeter (21) connected to generator (7). Second switch (11) is connected to inverter (12) via universal meter (13). Output of first switch (10) is connected to the input of second switch (11), by its output connected to tested motor (6). All devices for measuring electrical parameters and a tachometer are electrically connected to a personal computer.

EFFECT: broader functional capabilities and higher measurement accuracy.
